v1.301.0
Features
Switch to using NR fork of rrweb
Browser agent will now switch to using New Relic's forked version of rrweb for Session Replay instead of the original repository. This will allow browser team to custom tailor hotfixes for issues.
Bug fixes
Preserve agent attributes for log payloads
Adjust browser log payloads, such that agent-reserved attributes will take precedence over user-provided values if they happen to share the same name.

Address issues with dynamic require and Rollup.js

v1.299.0
Features
Add Flutter supportability metric
Introduces a supportability metric to track browser agent usage in Flutter web applications.
Add user frustration signals to UserAction
Provide better insight into potential user frustrations for specific user actions via dead click and error click detections.
Evaluate the accuracy of cross-feature attribution
To support internal improvement benchmarks, add supportability metrics that evaluate the accuracy of attributes that indicate the state of a separate event, such as hasReplay or hasTrace.
Bug fixes
Fix recordReplay API inconsistencies
Fixes an issue where a late-called recordReplay API call would not successfully harvest data.

v1.298.0
Features
Factor long tasks into soft nav base interaction span
BrowserInteraction under soft navigation ("SPA 2.0") will extend in duration beyond DOM modification time until the point wherein no long tasks have been observed for 5 seconds. JavascriptError and AjaxRequest are not yet associated with such interaction during this extended period beyond the end of the original heuristic.
Bug fixes
Force LCP to report the original page URL
Allow LCP to report its pageUrl distinctly from the harvest URL. An issue was observed where soft navigations occurring before the LCP harvest would report the current page URL instead of the original page URL tied to LCP. This change allows LCP harvest nodes to report the original URL, regardless of the current page URL. The change should apply both to the pageUrl and targetGroupedUrl attributes.

v1.297.0
Features
Prevent early harvests when in retry period
Prevent the agent from harvesting early when being rate limited. If the ingest service returns a 429, the agent will replace its data and try the harvest again later. While that is happening, it will no longer be able to harvest early as new data comes in, until it successfully harvests.
remove newrelic meta attribute
Remove the reporting of the __newrelic meta attribute from outgoing replay payloads. This is being conducted as a measure to help save billable bytes for customers and reduce cost of use for Session Replay functionalities.
Bug fixes
Fix exceptions for null bodies arising from empty harvests
A change has been made to enforce that all cleaned payloads ensure a valid output. Before, an empty string passing through the body cleaning process could throw an error as the mechanism would return the body as null. Now empty strings will pass through untouched, allowing further processing to apply successfully.

v1.296.0
Features
Harvest traces early
Update agent to handle session traces the same way other features handle data as of 1.294.0, by allowing harvests at 16kb of size.
Bug fixes
Remove event buffer inspection event
Removes the event buffer inspection event to avoid a memory leak on using console.log with the newrelic window event listener.

v1.295.0
Features
Add error cause detection
Detect and report the cause attribute on captured JavaScriptError events. If the cause is an instance of an Error, the stack trace will be captured, otherwise the stringified contents of the cause will be reported. This will be queryable in JavaScriptError events under the attribute cause.
Bug fixes
Add monkey-patching warnings
Added detection and warnings for when expected globals have been monkey-patched before the agent has been executed on the page. This can cause unexpected behaviors and the intent is to inform customers of this behavior.
Calculate first and last timestamps from raw data
Ensure the agent manually calculates the first and last timestamps of a SessionReplay payload before harvesting to help improve consistency on the UI replayer.

v1.294.0
Features
Harvest early
The agent will now be able to trigger early harvests if certain criteria is met. This will help ensure that more payloads are kept and memory leaks are prevented. The agent will initiate an early harvest when a feature buffer size reaches 16KB, otherwise it will continue to harvest every 30 seconds as before. This new behavior will apply to the following events:
- AjaxRequest
- BrowserInteraction
- BrowserPerformance
- Custom Events
- Log
- PageAction
- PageViewTiming
- SessionReplay
- UserAction
A separate effort will be conducted to enable early harvesting for timeslice metrics, javascript errors and session traces which use other mechanisms for storage in the agent.
Bug fixes
report empty previousUrl as undefined
The previousUrl attribute on BrowserInteraction events was reported as an empty string is cases where document.referrer is empty. This caused URL grouping to apply grouping on an empty string, leading to meaningless groups being appended to previousUrl. previousUrl is now reported as undefined to allow URL grouping to skip empty URLs.

Emit SM on rum response invalid timestamps
Emit a supportability metric on receiving an invalid timestamp in the rum call response.
